SM802112 ClockWorks™Frequency Synthesizer

The SM802112 is a member of the ClockWorks™ family of devices from Micrel and provides extremely low-noise clock signals. It is based upon a unique patented RotaryWave® architecture that provides very-low phase noise.

The device operates from a 3.3 V or 2.5 V power supply and synthesizes two LVDS output clocks, one at 480 MHz and one at 80 MHz and one LVCMOS clock at 80 MHz. The SM802112 accepts an 80 MHz LVCMOS reference clock or an 80 MHz 1 Vp-p sine wave.
